Hybrid fiber-coaxial (HFC) is a broadband telecommunications network that combines optical fiber and coaxial cable. It has been commonly employed globally by cable television operators since the early 1990s.

在电子工业出版社的《计算机网络》教材第四版上10．6．2章节中，ODN理解为Optical Distribution Node，即光分配节点。 指的是HFC（Hybrid Fiber Coax，光纤同轴混合网）中模拟光纤的光纤节点，用于连接模拟光纤。

2023年7月28日 · When the fiber optic line reaches the wall of your home, it goes into your fiber Optical Network Terminal (ONT) which works as a modem for fiber internet. Hybrid fiber coaxial (HFC) networks use a combination of fiber optic cable and coaxial cable [1].

2017年2月4日 · 光纖是通過無源光網絡設備ODN，分路後接到ONU的，ONU的上行為光口，借用戶埠為乙太網口可直接供用戶上網。 FTTH接入網中的千兆無源光網絡是一種點到多點的網絡 …

2024年9月6日 · Hybrid Fiber Coax (HFC) is a broadband telecommunications network that combines optical fiber and coaxial cable. Sometimes, we also referred it as HFC internet. In a hybrid fiber-coaxial cable system, television channels are sent from a Cable television headend to the local community over a fiber optic subscriber line.

该OLT提供了光信号和电信号之间的转换，经过本地电话公司路由器与因特网相连。 在家庭中，用户将一台家庭路由器 (通常是无线路由器)与ONT相连，并经过这台家庭路由器接人因特网。

OLT负责分配上行带宽到ONT。 因为光分布网络（ODN）是共享的，若ONT在随机时间发送数据则可能造成ONT上行传输的冲突（collide ）。 由于每个ONT与OLT的距离一定，其传输延迟也一定。

2024年4月7日 · HFC (Hybrid Fiber Coax) is a broadband telecommunications network that combines optical fiber and coaxial cable. It has been commonly employed globally by cable television operators since the early 1990s.

HFC 即Hybrid Fiber－Coaxial的缩写，是光纤和同轴电缆相结合的混合网络。 HFC通常由光纤干线、同轴电缆支线和用户配线网络三部分组成，从有线电视台出来的节目信号先变成光信号在干线上传输；到用户区域后把光信号转换成电信号，经分配器分配后通过同轴电缆 ...

Hybrid Fiber-Coax (HFC) is a telecommunications network architecture that combines two different types of transmission mediums, namely optical fiber and coaxial cable, to provide high-speed data, video, and voice services to homes and businesses. HFC networks are widely used by cable television and broadband internet service providers.
